Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

Fixed

  • OrderedDict has no .add() method — use key assignment for delivery dedup cache (66ad287)
  • Bash syntax error in SANDBOX_CMD (& &&) preventing runner from starting (8b9857f)
  • Label contention in test.yml — added job-${{ github.run_id }} unique label for 1:1 JIT runner binding (8b9857f)
  • ip6tables-legacy alternative registration crash during image rebuild (43825b0)

Changed

  • Dockerd wait + image load now run in background — runner starts immediately without waiting for Docker. Non-Docker jobs skip the 60s dockerd startup entirely. (43825b0)

Added

  • Multi-region support via MODAL_REGION environment variable
  • Custom sandbox environment variables via SANDBOX_EXTRA_ENV (JSON string)
  • Webhook secret rotation via WEBHOOK_SECRET_OLD fallback
  • Per-job metrics emission (job_complete logs with duration, GPU, region, error codes)
  • Matrix job example workflow (.github/workflows/matrix-example.yml)
  • Makefile for local development (deploy, serve, test, lint, logs)
  • Unit tests for GPU parsing, concurrency limits, network config, and health endpoint
  • Comprehensive CONTRIBUTING.md with setup, testing, and commit conventions

Changed

  • Updated DEPLOY.md with troubleshooting section and full environment variable reference
  • Updated README.md with badges, quickstart, feature/comparison tables, and GPU docs
  • Optimized runner image with uv_pip_install and removed unused packages

[2025-04-25] - v0.3.0

Added

  • Per-job GPU support via workflow labels (gpu:T4, gpu:A100, etc.) — T4, L4, A100, A100-80GB, H100
  • Network isolation via ALLOWED_CIDRS environment variable
  • Full network blocking via BLOCK_NETWORK environment variable
  • Persistent cache volume support via CACHE_VOLUME_NAME environment variable

[2025-04-25] - v0.2.0

Added

  • Structured JSON logging with contextual fields (job_id, repo, duration, status, error_code)
  • Health check endpoint (GET /health)
  • Retry logic for GitHub API calls with exponential backoff (1s/2s/4s, 3 attempts, 429/5xx)
  • Hardened payload validation with specific 400 error messages
  • Per-repo concurrency limits via MAX_CONCURRENT_PER_REPO environment variable
  • CI linting with ruff and pyproject.toml config
  • Unit test suite (23 tests) with pytest and pytest-asyncio
  • tests/** added to CI path triggers

Changed

  • Optimized runner image: removed unused packages (net-tools, sudo, jq), reordered layers for better caching
  • All logger calls updated from f-strings to structured extra={} pattern

[2025-04-24] - v0.1.0

Added

  • Initial release: Modal-powered ephemeral GitHub Actions runner
  • Docker-in-Sandbox support for container-based workflows
  • HMAC-SHA256 webhook signature verification
  • Repository allowlist via ALLOWED_REPOS
  • JIT runner registration for single-use tokens
  • Replay protection via delivery ID cache
  • Job deduplication cache
  • Configurable runner version, group ID, and labels
  • GitHub Enterprise domain support
  • Body size limit (1MB)
  • Automated CI/CD via GitHub Actions
